Description
本發明係有關於一種細化裝置，特別是有關於一種能夠產生大量易溶解於水的微細氣泡的細化裝置。本發明還涉及此細化裝置產生微細氣泡的方法及此細化裝置之氣閥轉接座。 The present invention relates to a refining device, and more particularly to a refining device capable of generating a large amount of fine bubbles which are easily dissolved in water. The invention also relates to a method of producing fine bubbles by the refining device and a valve adapter of the refining device.
養殖漁業、農業或一般室內設置之水族箱常常會因為水槽容室容積上的限制，導致水中之存氧量、存二氧化碳量或其它氣體含量不足，因此難以供給所有水中之動植物使用。因此，養殖業者經常會利用高壓氣體鋼瓶或其它氣體供應裝置透過氣體細化裝置氣體打入水中，來增加水槽、水池或水族箱中水的含氧量或二氧化碳含量，以供水中之動植物使用，例如，從事水草或藻類養殖時，常常需要利用CO2細化器將CO2打入水族箱之水中，使CO2溶解於水而被水吸收中，以供植物使用。 Aquariums in aquaculture, agriculture or general indoor installations often have insufficient oxygen storage, carbon dioxide or other gas content in the water due to the limitation of the volume of the tank chamber, so it is difficult to supply the animals and plants in all water. Therefore, the aquaculture industry often uses high-pressure gas cylinders or other gas supply devices to enter the water through the gas refining device gas to increase the oxygen content or carbon dioxide content of the water in the water tank, the pool or the aquarium, and use the plants and animals in the water supply. For example, when engaged in aquaculture or algae farming, it is often necessary to use a CO2 refiner to drive CO2 into the water of the aquarium, so that the CO2 is dissolved in the water and absorbed by the water for use by the plant.
然而，習知技藝之細化裝置使用上卻有著諸多的限制。請參閱第1A及1B圖，係為習知技藝之細化裝置之示意圖。習知技藝之細化裝置1通常利用高壓氣體鋼瓶將氣體通過多孔陶瓷、透氣木及氣泡石等等細化介質以在水中產生氣泡，這些細化介質通常為粗糙多孔隙的陶瓷材質製成，然而，由於陶瓷材質製品之孔洞是亂數分配的，如第1B圖所示，因此多孔陶瓷10內形成的路徑是由多個孔洞隨機疊合而成，是彎彎曲曲的不規則狀，每一的路徑上只要有一孔阻塞，透氣效果便會大幅降低甚至完全無法出氣。 且藻類植物及水中汙染源是非常容易阻塞或著床於粗糙、多孔隙且平均孔徑>10μm的細化介質上，因此多孔陶瓷10在使用數天後很容易堵塞，且一旦著床，幾乎無法清除，常常在使用後約一個星期後即完全阻塞，需要直接更換新品，使用上成本較高。 However, there are many limitations to the use of the refinement device of the prior art. Please refer to Figures 1A and 1B for a schematic view of a refinement device of the prior art. The refining device 1 of the prior art generally uses a high-pressure gas cylinder to pass a gas through a porous medium, a gas permeable wood, a bubble stone, or the like to refine bubbles in the water, and the refining medium is usually made of a coarse porous ceramic material. However, since the holes of the ceramic material are randomly distributed, as shown in FIG. 1B, the path formed in the porous ceramic 10 is formed by randomly overlapping a plurality of holes, and is an irregular shape of bending and bending. As long as there is a hole in the path of one block, the ventilation effect will be greatly reduced or even completely unable to vent. The algae plant and the water pollution source are very easy to block or implant on the rough, porous and fine medium with an average pore diameter of >10 μm, so the porous ceramic 10 is easily clogged after several days of use, and once it is implanted, it can hardly be removed. It is often completely blocked after about one week after use, and it is necessary to replace the new product directly, which is costly to use.
此外，如同上述，多孔陶瓷10很容易被藻類植物及水中汙染源所阻塞，故需要將其工作面積加大，以減少阻塞的機會，故也增加了它體積的大小。因此，使用於水族箱中容易影響水族箱造景的配置，影響其美觀性。 In addition, as described above, the porous ceramic 10 is easily blocked by algae plants and water pollution sources, so it is necessary to increase the working area to reduce the chance of clogging, thereby increasing its volume. Therefore, it is easy to affect the configuration of the aquarium landscaping in the aquarium, which affects its aesthetics.
另外，多孔陶瓷10是沒有彈性的易碎物質，其耐壓較低(約為30PSI)，通常超過25PSI即有可能會因壓力過大而破裂，這大幅地增加了養殖業者的使用成本。又，如同上述，多孔陶瓷10內形成的路徑多個大小不均的孔洞無規則疊合而成，故孔洞大小不均且孔徑較大，孔徑大小不均造成其透氣效率難以維持一致，且由於氣體溶解不易，因此高壓氣體鋼瓶之氣體流量需要加強以維持氣體於水中的濃度，故不易控制水中氣體的濃度，常因氣體濃度過高而導致水中動物或植物死亡。而孔徑較大其所能產生的氣泡也較大，如圖中所示，較大的氣泡由於水中浮力較大，因為其在水中上升的也更快，故會很快的到達水面，故還來不及溶解於水就散失於空氣中，較大的氣泡與水的總接觸面積也較小，故其在水中溶解較為不易，效能上有著很大的限制。 In addition, the porous ceramic 10 is a fragile material which is inelastic and has a low withstand voltage (about 30 PSI). Usually, it is likely to be broken due to excessive pressure when it exceeds 25 PSI, which greatly increases the cost of use by the aquarist. Moreover, as described above, a plurality of holes of uneven size formed in the porous ceramic 10 are irregularly stacked, so that the size of the holes is uneven and the aperture is large, and the pore size is uneven, so that the gas permeability efficiency is difficult to maintain, and The gas is not easily dissolved, so the gas flow rate of the high-pressure gas cylinder needs to be strengthened to maintain the concentration of the gas in the water, so it is difficult to control the concentration of the gas in the water, and the animal or plant in the water is often killed due to the high gas concentration. The larger the aperture, the larger the bubble can be generated. As shown in the figure, the larger bubble has a larger buoyancy in the water, because it rises faster in the water, so it will reach the surface quickly, so If it is too late to dissolve in water, it will be lost in the air. The larger contact area between the larger bubbles and water is also smaller, so it is not easy to dissolve in water, and there is a great limit on the efficiency.
而由於透過多孔陶瓷10產生的氣泡溶解效率不佳，因此供氣的高壓氣體鋼瓶需要供給更多的氣體，故耗費的也快，故也經常的需要更換。 However, since the bubble generated by the porous ceramic 10 is inefficient in dissolving, the high-pressure gas cylinder supplied with the gas needs to supply more gas, so it is also expensive, so it is often required to be replaced.
因此，如何提出一種細化裝置，能夠改善習知技藝之細化裝置容易阻塞、效能不佳、成本居高不下、易破裂、使用壽命短及透氣效率不穩定難以一致等缺點已經成為了一個刻不容緩的問題。 Therefore, how to propose a refinement device, which can improve the conventional technology, the refinement device is easy to block, the performance is not good, the cost is high, the rupture, the service life is short, and the ventilation efficiency is unstable and difficult to be consistent has become an urgent task.

氣槽21可透過氣體輸送管24與氣體供應器23連結，使氣體供應器23能透過氣體輸送管24輸送氣體至氣槽21，氣體供應器23可為例如空氣幫浦或是高壓氣體鋼瓶等等多種裝置。而微細孔薄膜22則可以設置於氣槽21之出氣口上。 The gas tank 21 can be connected to the gas supply unit 23 through the gas delivery pipe 24, so that the gas supply device 23 can deliver gas to the gas tank 21 through the gas delivery pipe 24. The gas supply unit 23 can be, for example, an air pump or a high pressure gas cylinder. A variety of devices. The fine pore film 22 can be disposed on the gas outlet of the gas tank 21.
如圖中所示，氣體供應器23能透過氣體輸送管24輸送加壓氣體至氣槽21，並使加壓氣體透過氣槽21上出氣口之微細孔薄膜22噴出，使水槽2中之水中產生大量微細氣泡。其中，微細孔薄膜22可透過多種方式製成，例如雷射加工，其孔徑大約可以在30μm以下，較佳的可在3-20μm，因此能產生習知技藝之細化裝置無法產生的微細氣泡。然而，本發明主要是提出以薄膜式的設計，在細化裝置中使用微細孔薄膜來產生微細氣泡，上述之加工方式及孔徑大小僅為舉例說明而已，本發明有多種實施態漾，並不受到上述加工方式及孔徑大小的限制。微細孔薄膜22的在材質上也沒有特殊的限制，其可以為塑膠或金屬等材質製成。 As shown in the figure, the gas supply unit 23 can deliver the pressurized gas to the gas tank 21 through the gas delivery pipe 24, and the pressurized gas can be ejected through the microporous film 22 of the gas outlet port of the gas tank 21 to make the water in the water tank 2 A large amount of fine bubbles are generated. The microporous film 22 can be formed by various methods, such as laser processing, and the pore diameter can be about 30 μm or less, preferably 3-20 μm, so that microbubbles which cannot be produced by the refinement device of the prior art can be generated. . However, the present invention mainly proposes a film-type design in which a fine pore film is used in a refining device to generate fine bubbles. The above-described processing method and pore size are merely illustrative, and the present invention has various embodiments, and Limited by the above processing methods and aperture size. The microporous film 22 is also not particularly limited in material, and may be made of a material such as plastic or metal.
值得一提的是，養殖業通常需要將氣體強制溶於水中，這些氣體通常主要包含有空氣、氧氣及二氧化碳，這些氣體都屬於略溶於水的特性，而習知技藝之細化裝置通常利用多孔陶瓷、透氣木及氣泡石等等將上述氣體 強制溶於水中，以在水中產生氣泡，這些元件大都以陶瓷材質製成，由於陶瓷材質本身的限制，其所產生的氣泡較大，氣泡之粒徑大約為20~500μm，顆粒較大且不一致，而較大的氣泡於水中浮力愈大，上升愈快，在水中停留時間愈短，故很難在水中溶解，因此很難增加水中的含氧量、含二氧化碳量或其它氣體含量，效能較為低落。 It is worth mentioning that the aquaculture industry usually needs to force the gas to be dissolved in water. These gases usually contain air, oxygen and carbon dioxide. These gases are all slightly soluble in water, and the refinement devices of the prior art usually use Porous ceramics, gas permeable wood, bubble stones, etc. Forced to dissolve in water to create bubbles in water. Most of these components are made of ceramic materials. Due to the limitation of ceramic materials, the bubbles generated by them are large. The particle size of bubbles is about 20~500μm. The particles are large and inconsistent. The larger the buoyancy in the water, the faster the rise, the shorter the residence time in the water, so it is difficult to dissolve in water, so it is difficult to increase the oxygen content, carbon dioxide content or other gas content in the water. low.
相反的，本發明之細化裝置能夠透過孔徑在30μm以下之微細孔薄膜產生大量均勻的微細氣泡於水中，較小的氣泡於水中浮力小，上升較慢，在水中停留時間愈長，易於水中溶解，且由於相同總體積的氣泡群，若顆粒越細則與水接觸的表面積總和越大，愈容易地溶解進入水中，有效增加水中的含氧量、含二氧化碳量或其它氣體含量，因此也具備較高的效能。另外，由於本發明之細化裝置所產生的微細氣泡極易溶解於水中，因此不需要注入太多氣體於水中，故相對於習知技藝，本發明之細化裝置同樣容積的加壓氣體鋼瓶的使用時間更長，經測試鋼瓶使用時間為習知技藝多孔陶瓷的三倍，有效地降低其使用上的成本。 On the contrary, the refining device of the present invention can generate a large amount of uniform fine bubbles in the water through the microporous film having a pore diameter of 30 μm or less, and the smaller bubbles have less buoyancy in the water, and the rise is slower, and the longer the residence time in the water, the easier the water is. Dissolved, and due to the same total volume of the bubble group, if the total surface area of the particles in contact with water is larger, the easier it is dissolved into the water, effectively increasing the oxygen content, carbon dioxide content or other gas content in the water, so Higher performance. In addition, since the fine bubbles generated by the refining device of the present invention are extremely soluble in water, it is not necessary to inject too much gas into the water, so the refining device of the present invention has the same volume of pressurized gas cylinder as compared with the prior art. It lasts for a longer period of time, and the tested cylinders are used three times longer than conventional ceramics, effectively reducing the cost of their use.
又，由上述可知，多孔陶瓷內形成的路徑是由多個大小不同的孔洞隨機疊合而成，是彎彎曲曲的不規則狀，故產生之氣泡大小不均勻，且每片多孔陶瓷的品質等也不相同，造成其透氣效率難以掌握，氣體於水中的濃度不易控制，且由於氣體在水中溶解不易，故加壓氣體鋼瓶需要放出更多的氣體，以維持水中氣體濃度。因此，常因為意外注入水中的二氧化碳濃度過高而使水槽中之魚類等等動物死亡的情況。相反的，本發明之細化裝置使用之微細孔薄膜是利用特殊工法製成，孔徑大小容易控制，產生氣泡大小均勻，每片薄膜的品質相同，透氣效率容易掌握，且氣體溶解率高，故加壓氣體鋼瓶僅需要放出少量氣體即可輕易控制氣體於水中的濃度，使用上有更高的精確度，安全性更高。 Further, as apparent from the above, the path formed in the porous ceramic is formed by randomly stacking a plurality of holes having different sizes, and is an irregular shape which is curved and curved, so that the bubble size is uneven, and the quality of each porous ceramic is obtained. The same is not the same, which makes the gas permeability difficult to grasp, the concentration of gas in water is difficult to control, and because the gas is not easily dissolved in water, the pressurized gas cylinder needs to release more gas to maintain the gas concentration in the water. Therefore, it is often the case that the fish in the sink and the like die due to the excessive concentration of carbon dioxide in the accidental injection water. On the contrary, the microporous film used in the refining device of the present invention is made by a special working method, the pore size is easily controlled, the bubble size is uniform, the quality of each film is the same, the gas permeability efficiency is easy to grasp, and the gas dissolution rate is high, so Pressurized gas cylinders only need to release a small amount of gas to easily control the concentration of gas in water, with higher precision and higher safety.
請參閱第3圖，係為本發明之細化裝置之第一實施例之第二示意圖。如同前述，微細孔薄膜22上可以利用多種方式，如雷射加工等等方法來製造出孔徑極小的微細孔洞221，例如30μm以下，其它的應用甚至可以達到±5μm左右，產生極為細小的微細氣泡，故彈性很大，除此之外，各個微細孔洞221還可以是上窄下寬之圓錐狀，愈靠近氣槽的那一側具有愈大的孔徑，而接觸水的那一側則具有愈小的孔徑。如此的設計能夠使氣泡不易堆積，使產生氣泡的體積可以一直維持的很小，另外，微細孔薄膜22的耐壓較高不易損壞，而藻類也不易著床阻塞，也不易因為砂土及排泄物堆積而阻塞，使用壽命較長。需注意的是，本發明之微細孔薄膜22如同其名稱，是一片極薄的薄片，然而本圖由於要完整表達本發明之技術特徵，因此在本圖中已將其誇大，但本發明並不以此為限。 Please refer to FIG. 3, which is a second schematic view of the first embodiment of the refining device of the present invention. As described above, the fine pore film 22 can be manufactured by various methods such as laser processing or the like to produce fine pores 221 having a very small pore diameter, for example, 30 μm or less, and other applications can even reach about ±5 μm, resulting in extremely fine microbubbles. Therefore, the elasticity is large, and in addition, each of the fine holes 221 may have a conical shape with a narrow upper and a lower width, a larger aperture on the side closer to the gas groove, and a side closer to the water. Small aperture. Such a design can make the bubbles less likely to accumulate, so that the volume of the generated bubbles can be kept small at all times. In addition, the pressure resistance of the microporous film 22 is relatively high and is not easily damaged, and the algae is not easily blocked by the bed, and is also difficult to be sand and excreted. The material is stacked and blocked, and the service life is long. It should be noted that the microporous film 22 of the present invention, like its name, is an extremely thin sheet. However, since this figure is to fully express the technical features of the present invention, it has been exaggerated in the present drawing, but the present invention Not limited to this.
請參閱第4圖，係為本發明之細化裝置之第一實施例之第三示意圖。如圖所示，本發明主要是提出將微細孔薄膜22固定於氣槽21之出氣口上(氣閥轉接座)，使得加壓氣體鋼瓶注入氣槽21之氣體能透過微細孔薄膜22進入水中而產生多個微細氣泡。而微細孔薄膜22可利用具有一定彈性的材質所製成，例如塑膠或金屬，因此耐壓較高，連接加壓氣體鋼瓶不易損壞，使用壽命較長，且也可用於空氣幫浦，使用上更具彈性及多樣化。相反的，由於多孔陶瓷材質上缺乏彈性，故極容易破碎，且其耐壓約僅有30PSI，而加壓氣體鋼瓶之壓力則高達2000PSI，故只要使用上稍有不甚，多孔陶瓷即會破裂，也因為多孔陶瓷缺乏彈性，(故只能用於加壓氣體鋼瓶，無法使用於空氣幫浦)所以當使用不同的加壓源時(如空氣幫浦)需外接穩壓或降壓裝置，或需依不同的加壓源，改變不同配方的陶瓷組成來因應。相較之外，本發明使用上更為方便。 Please refer to FIG. 4, which is a third schematic view of the first embodiment of the refining device of the present invention. As shown in the figure, the present invention mainly proposes that the microporous film 22 is fixed to the air outlet of the air tank 21 (valve valve adapter), so that the gas injected into the air tank 21 of the pressurized gas cylinder can pass through the microporous film 22 to enter. A plurality of fine bubbles are generated in the water. The microporous film 22 can be made of a material having a certain elasticity, such as plastic or metal, so that the withstand voltage is high, the pressurized gas cylinder is not easily damaged, the service life is long, and the air pump can also be used. More flexible and diverse. On the contrary, due to the lack of elasticity on the porous ceramic material, it is extremely easy to break, and its pressure resistance is only about 30 PSI, while the pressure of the pressurized gas cylinder is as high as 2000 PSI, so the porous ceramic will rupture as long as it is used slightly. Also, because porous ceramics lack elasticity, they can only be used in pressurized gas cylinders and cannot be used in air pumps. Therefore, when using different pressurized sources (such as air pumps), an external voltage regulator or step-down device is required. Or according to different pressure sources, change the ceramic composition of different formulations to respond. In contrast, the invention is more convenient to use.
值得一提的是，習知技藝之細化裝置通常利用多孔陶瓷、透氣木及氣 泡石等等來在水中產生氣泡，而這些元件常使用陶瓷材質製成，由於陶瓷材質之孔洞之孔徑較大，故藻類容易著床於其上而產生阻塞，而砂土及排泄物也容易堆積於其中而阻塞，一但阻塞了清理上也極為困難，這對其使用壽命有很大的影響，通常使用數天至一星期後即無法繼續使用，需要更換新品，又容易因壓力過高而破裂，對養殖業者而言是很大的成本負擔。相反的，本發明之細化裝置使用微細孔薄膜，微小的孔徑及特殊的孔洞設計使藻類不易著床阻塞，也不易因為砂土及排泄物堆積而阻塞，不容易因壓力而破裂，因此使用壽命長及成本也較低。由上述可知，本發明實具進步性之專利要件。 It is worth mentioning that the refinement of conventional techniques usually uses porous ceramics, ventilated wood and gas. Bubbles and the like to generate bubbles in water, and these components are often made of ceramic materials. Since the pores of the ceramic material have a large pore size, the algae are easily placed on the bed to cause blockage, and the sand and excrement are also easy. It is extremely difficult to accumulate in it, but it is extremely difficult to clean up. It has a great influence on its service life. It usually cannot be used after several days to one week. It needs to be replaced with new products and it is easy to be over-stressed. The rupture is a great cost burden for the breeder. On the contrary, the refining device of the present invention uses a microporous film, the micro pore size and the special hole design make the algae difficult to be blocked by the bed, and it is not easy to be blocked by the accumulation of sand and excrement, and is not easily broken by pressure, so it is used. Long life and low cost. As can be seen from the above, the present invention has progressive patent requirements.
請參閱第5圖，係為本發明之細化裝置之第一實施例之第四示意圖。如圖所示，當本發明之細化裝置2實際使用時，能在水中產生大量的微細氣泡，此微細氣泡由於體積較小，浮力小，在水中上升較慢，且與水接觸總面積較大，故極易容於水，通常未達到水面即能全面溶解完畢。相反的，如第1A圖所示，習知技藝之細化裝置1產生的大氣泡浮力大，故會快速升至水面，與水接觸總面積也較小，氣體的溶解率遠低於本發明之細化裝置2。 Please refer to FIG. 5, which is a fourth schematic diagram of the first embodiment of the refining device of the present invention. As shown in the figure, when the refining device 2 of the present invention is actually used, a large amount of fine bubbles can be generated in water, and the microbubbles are relatively small in volume, have small buoyancy, rise slowly in water, and have a total area of contact with water. Large, it is very easy to accommodate water, usually can not be fully dissolved after reaching the water surface. On the contrary, as shown in FIG. 1A, the large bubble generated by the refinement device 1 of the prior art has a large buoyancy, so that it will rapidly rise to the water surface, and the total area of contact with water is also small, and the dissolution rate of the gas is much lower than the present invention. Refinement device 2.
請參閱第6圖，係為本發明之細化裝置之第二實施例之示意圖。本發明之細化裝置2可以廣泛使用於各種不同的應用。例如，用於水族箱中培養水草、各種藻類(提升水中之二氧化碳含量)或魚蝦(提升水中之氧氣含量)，或用於養殖各類魚蝦貝類等等之養殖漁業(提升水中之氧氣含量)及養殖蔬菜或藻類之水耕農業(提升水中之二氧化碳含量)，也可以用於臭氧消毒。如圖所示，本發明之細化裝置2應用於水族箱中養殖魚類，設置多個細化裝置2於水槽25中，由於本發明之細化裝置2具備較高的效能，因此所需要的數量也比習知技藝之細化裝置少，成本也較低。 Please refer to FIG. 6 , which is a schematic view of a second embodiment of the refining device of the present invention. The refining device 2 of the present invention can be widely used in a variety of different applications. For example, for the cultivation of aquatic plants in the aquarium, various algae (to raise the carbon dioxide content in the water) or fish and shrimp (to increase the oxygen content in the water), or for the breeding of various types of fish, shrimps and shellfish, etc. (to raise the oxygen content in the water) And hydroponics farming of vegetables or algae (increasing the carbon dioxide content in water) can also be used for ozone disinfection. As shown in the figure, the refining device 2 of the present invention is applied to farmed fish in an aquarium, and a plurality of refining devices 2 are provided in the water tank 25. Since the refining device 2 of the present invention has high performance, it is required The quantity is also less than the refinement device of the prior art, and the cost is also low.
值得一提的是，習知技藝之多孔陶瓷很容易被藻類植物及水中汙染源 所阻塞，故需要將其工作面積加大，以減少阻塞的機會，一般而言，多孔陶瓷所需要的工作面積大約為Φ30~Φ50mm，單體體積大約為Φ45~Φ60*h：50~150mm，較大的體積會影響水族箱造景的配置，影響其美觀性。相反的，本發明之細化裝置由於是用薄膜式的設計，不易阻塞，故工作面積不必太大，在一實施例中，工作面積可為Φ6mm，單體體積可為Φ30mm*L30mm，並且可依需求來訂製調整，其體積可遠小於習知技藝之多孔陶瓷，因此，本發明之細化裝置使用於水族箱中可以隱藏於水草中，或直接埋入沙中，微細氣泡仍可以由砂中散佈出來，不會影響到水族箱之造景配置及美觀性，使細化裝置能具備更高的實用性。 It is worth mentioning that the porous ceramics of the known art are easily contaminated by algae and water. Obstructed, it is necessary to increase the working area to reduce the chance of blocking. Generally speaking, the working area required for porous ceramics is about Φ30~Φ50mm, and the volume of the monomer is about Φ45~Φ60*h: 50~150mm. The larger volume affects the configuration of the aquarium landscaping and affects its aesthetics. On the contrary, the refining device of the present invention is not easy to block because of the membrane type design, so the working area does not have to be too large. In one embodiment, the working area can be Φ6 mm, and the unit volume can be Φ30 mm*L30 mm, and Customized adjustment according to requirements, the volume can be much smaller than the porous ceramics of the prior art. Therefore, the refining device of the present invention can be hidden in the aquatic plants in the aquarium or directly buried in the sand, and the microscopic bubbles can still be Dispersed in the sand will not affect the landscaping configuration and aesthetics of the aquarium, so that the refining device can have higher practicality.
儘管前述在說明本發明之細化裝置的過程中，亦已同時說明本發明之產生微細氣泡的方法的概念，但為求清楚起見，以下仍然列出本發明之產生微細氣泡的方法之流程。 Although the concept of the method for producing fine bubbles of the present invention has been simultaneously described in the foregoing description of the refining device of the present invention, for the sake of clarity, the flow of the method for producing fine bubbles of the present invention is still listed below. .
請參閱第7圖，係為本發明之產生微細氣泡的方法之流程圖。 Please refer to Fig. 7, which is a flow chart of the method for producing fine bubbles in the present invention.
本發明之產生微細氣泡的方法可包含下列步驟： The method of producing fine bubbles of the present invention may comprise the following steps:
在步驟S71中，提供一氣體供應器。 In step S71, a gas supply is provided.
在步驟S72中，利用氣體供應器透過氣體輸送管將加壓氣體輸送至氣槽。 In step S72, the pressurized gas is delivered to the gas tank through the gas delivery pipe by the gas supply.
在步驟S73中，使加壓氣體透過氣槽之出氣口之一微細孔薄膜之複數個微細孔洞噴出，使水中產生大量微細氣泡。 In step S73, a plurality of fine pores of the fine pore film which is passed through the gas outlet of the gas tank are ejected, and a large amount of fine bubbles are generated in the water.
本發明之產生微細氣泡的方法的詳細說明以及實施方式已經於前面敘述本發明之細化裝置時描述過，在此為了簡略說明便不再重覆敘述。 The detailed description and embodiments of the method for producing fine bubbles of the present invention have been described in the foregoing description of the refining device of the present invention, and will not be repeated here for the sake of brevity.
綜上所述，本發明之細化裝置使用微細孔薄膜，因此能於水中產生數量極多的微細氣泡，而微細氣泡極易於水，故較習知技藝之細化裝置更能有效提升水中之含氧量、含二氧化碳量或其它氣體含量，因此具有較高的 效能。而由於本發明之細化裝置效能較高，故供氣的高壓氣體鋼瓶或空氣幫浦電力上的耗費也能降低，能有效地減少使用者之成本。本發明之細化裝置之微細孔薄膜之孔徑極小，使藻類不易著床阻塞，也不易因為砂土及排泄物堆積而阻塞，使用上的壽命也較長。本發明之細化裝置產生之微細氣泡細小且均勻，因此很容易就能控制氣體於水中的濃度，使其不至於過高或過低，使用上較為穩定及安全。在者，本發明之細化裝置產生之微細氣泡較習知技藝之細化裝置小，且效率較高，氣體的耗費量來的較低，所需要設置之數量也較少，能夠節省大量的成本，且不但能用於高壓氣體鋼瓶，也可用於空氣幫浦，使用彈性更大。而又因本發明之細化裝置採用微細孔薄膜，薄膜式的設計使裝置的體積遠比習知技藝之多孔陶瓷小，因此不會影響水族箱或水槽之整體配置及美觀，使用上極具方便性。 In summary, the refining device of the present invention uses a microporous film, so that a large number of fine bubbles can be generated in water, and the fine bubbles are extremely easy to be water, so that the refining device of the prior art can effectively raise the water. Oxygen content, carbon dioxide content or other gas content, therefore having a higher efficacy. However, since the refining device of the present invention has high performance, the cost of the high-pressure gas cylinder or the air pump power supplied to the gas can also be reduced, and the cost of the user can be effectively reduced. The microporous membrane of the refining device of the present invention has a very small pore diameter, which makes the algae difficult to be blocked by the bed, and is not easily blocked by the accumulation of sand and excrement, and has a long service life. The fine bubbles generated by the refining device of the present invention are fine and uniform, so that it is easy to control the concentration of the gas in the water so as not to be too high or too low, and the use is relatively stable and safe. In addition, the fine bubbles generated by the refining device of the present invention are smaller than the refinement device of the prior art, and the efficiency is high, the gas consumption is low, and the number of settings required is small, which can save a large amount of Cost, and can be used not only for high-pressure gas cylinders, but also for air pumps, which are more flexible. Moreover, since the refining device of the present invention adopts a microporous film, the film type design makes the device much smaller than the porous ceramics of the prior art, and thus does not affect the overall configuration and appearance of the aquarium or the sink, and is extremely suitable for use. Convenience.
